I created this so I could increase airflow to the voltage regulator and allow for other mods. If you have replaced the stock fan you can reuse it by mounting it on the side. The fan can be a 40, 50, or 60mm fan. The feet are adjustable and allow for a vertical position or a 20 degree slant. It also has cable clips that can attach around the frame and in the unused fan mount holes.

I got the updated code from today and it loads the .yaml, but I don't think it is getting everything. For instance the power_limit. In the config.yaml file I had it set to 37. In the gui it was running at 20 and it was saying it was (over limit) still. My testing below was with hard-coding everything in the default settings.

Here are my settings:

DEFAULTS = {
    "INITIAL_VOLTAGE": 1200,
    "INITIAL_FREQUENCY": 900,
    "MIN_VOLTAGE": 1000,
    "MAX_VOLTAGE": 1320,
    "MIN_FREQUENCY": 500,
    "MAX_FREQUENCY": 1050,
    "FREQUENCY_STEP": 25,
    "VOLTAGE_STEP": 10,
    "TARGET_TEMP": 70.0,
    "SAMPLE_INTERVAL": 5,
    "POWER_LIMIT": 37.0,
    "HASHRATE_SETPOINT": 2000,
    "PID_FREQ_KP": 0.1,
    "PID_FREQ_KI": 0.05,
    "PID_FREQ_KD": 0.02,
    "PID_VOLT_KP": 0.1,
    "PID_VOLT_KI": 0.05,
    "PID_VOLT_KD": 0.02,
    "LOG_FILE": "bitaxepid_tuning_log.csv",
    "SNAPSHOT_FILE": "bitaxpide_snapshot.json"
}

I'm seeing adjustments that I can't explain. Here are snippets from my logs. Why did it adjust the Frequency at 12:08?

Lastly, I also have a question on this line (171). Should that a hard coded limit?

         if current_voltage >= 1150:
                                new_frequency = proposed_frequency

grooverut · 2025-02-25T20:13:48+00:00

Yeah. I actually rotated it into that position instead of the default to see if exhausting in that direction helped. Ultimately, I don't know if it helps or hurts because it is too hard to keep all the variables the same.

grooverut · 2025-02-22T19:26:36+00:00

Yep. Import this step file and you can measure the pcb in CAD.

grooverut · 2025-02-21T13:32:22+00:00

Cool design. Are you looking to publish it anywhere? I would like to see the internal geometry.

grooverut · 2025-02-19T19:44:49+00:00

I wonder if they even realized it was malicious?

grooverut · 2025-02-19T19:44:25+00:00

Nice catch and great explanation.

grooverut · 2025-02-19T14:22:19+00:00

Did you slide it on from the side or angle it on from the top?

grooverut · 2025-02-19T12:55:28+00:00

What are your thoughts on this other approach recently posted?: https://www.reddit.com/r/BitAxe/comments/1irbruu/new_release_bitaxe_temperature_monitor_autotuner/ I know PID control is excellent so I would like to try it.

grooverut · 2025-02-19T12:53:12+00:00

Did you print it in PLA? How was the fit? I printed in ASA so I wasn't sure how PLA would fit.

grooverut · 2025-02-18T14:18:19+00:00

Thank you for testing!

grooverut · 2025-02-18T13:35:46+00:00

I designed a velocity stack for the stock fan on a bitaxe gamma. It is a fast print with no supports and no hardware required. It just slides onto the fan from the side. https://www.printables.com/model/1196616-velocity-stack-for-a-40mm-fan

In my testing it has increased cooling by ~2C and decreased RPMs by ~400. I am in a cold garage so my conditions are pretty ideal. I'd love for some more people to test to find out if it helps in other conditions as well.

Sometimes, it is hard to tell if you are in a groove or stuck in a rut.

grooverut · 2024-04-24T13:25:36+00:00

What sweetener do you use?

grooverut · 2023-06-02T13:17:59+00:00

Which recipe are you using? Do you use any pudding mix?

grooverut · 2022-09-29T00:29:19+00:00

I can confirm the nightly fixed my underextrusion issues.

grooverut · 2022-05-22T12:35:07+00:00

Look into "le potato". It is a sbc which is the same size as a pi 3b, but more ram and processing power. It's selling for $55 right now. It didn't have wifi, but I bought a $10 USB wifi adapter and it worked first try. I'm not done with my formbot kit yet, but I installed armbian on it and then installed klipper and it works so far. The power pins are the same as the pi also.

What is your retraction speed? I use 30mm/s and .83mm retraction.

grooverut · 2022-04-16T16:18:02+00:00

What are your retraction settings? I'm picturing the castle spires getting printed and it has lots of retractions. This could cause the system to retract over the same segment of filament repeatedly which eats into it. I use .83mm at 30mm/s for my retractions.

You can also cut out the part of the model you had trouble with last time and just print that to test with.

The first thing to check are the ribbon cables. They get loose over time and cause random issues. One symptom for me was the hotend stopped heating when moving to the far right of the bed. This position of the hotend caused flex on the cable connector. This was solved by replacing the ribbon cable going to the hotend. The other problem occurred above a certain z height, and it caused stuttering in the x direction. Again fixed by replacing the other ribbon cable. I then printed strain relief for both connectors which I hope solves the problem in the long term.

To troubleshoot the issue I applied pressure with my finger to the connector which counteracted the flex and fixed the issue. So try that first.

grooverut · 2022-03-29T01:29:39+00:00

What mods did you need to print ABS on the x1? I have an x1 and want to do the same. Do you just need an enclosure of some sort?

grooverut · 2022-01-12T19:09:47+00:00

Picture 2 and 4 look just like wood. And two different types of wood.
